An active cooling system and method for using the active cooling system are described. The active cooling system includes a cooling element having a first side and a second side. The first side of the cooling element is distal to a heat-generating structure and in communication with a fluid. The second side of the cooling element is proximal to the heat-generating structure. The cooling element is configured to direct the fluid using a vibrational motion from the first side of the cooling element to the second side such that the fluid moves in a direction that is incident on a surface of the heat-generating structure at a substantially perpendicular angle and then is deflected to move along the surface of the heat-generating structure to extract heat from the heat-generating structure.

A linear fan including a fan blade attached a fan frame by a wire spring having a first end attached to the fan blade and a second end attached to the fan frame. The fan blade includes a free end such that the blade oscillates by pivoting on the wire spring. The the wire spring flexes to enable the fan blade to oscillate. The fan includes a motor for driving the oscillation of the fan blade. The motor includes an armature or permanent magnet connected to the fan blade and a stator assembly connected to the fan frame. The stator assembly includes a current carrying coil wrapped around a leg of a stator core. The motor is controlled to vary the direction of the current being carried in the coil to thereby change the direction of the magnetic field created by the stator assembly and cause the fan blade to oscillate.

An operating characteristic of an information handling system is determined. It is determined whether a cooling configuration of a plurality of piezoelectric cooling fans included at the information handling system is providing a designated level of cooling. A cooling profile is stored at a memory device, the cooling profile including the operating characteristic and the cooling configuration.

A system for thermal management of a heat sink via active surfaces. The heat sink includes a cavity within the heat sink, and a nozzle. The nozzle provides a pathway from the cavity to a surface of the heat sink. The heat sink also includes a membrane attached to the cavity and an actuator of the membrane, causing the membrane to oscillate. The oscillation of the membrane causes inflow and outflow of a medium through the nozzle.

Exemplary air amplifiers described herein can utilize a high-pressure stream of gas to accelerate a low-velocity stream of gas to provide a high-velocity, high-volume stream of gas. This high-velocity, high-volume stream of gas can generate unwanted noise as the high-velocity, high-volume stream of gas propagates through the air amplifier. The exemplary air amplifiers described herein can passively and/or actively suppress, for example, diminish, re-tune, or even completely cancel, the unwanted noise as the high-velocity, high-volume stream of gas propagates through these exemplary air amplifiers. The exemplary air amplifiers described herein can include one or more absorption materials to passively suppress the unwanted noise generated by the high-velocity, high-volume stream of gas. The exemplary air amplifiers described herein can generate multiple noise suppression waves to actively suppress the unwanted noise generated by the high-velocity, high-volume stream of gas. The multiple noise suppression waves can destructively combine with the unwanted noise generated by the high-velocity, high-volume stream of gas to suppress the unwanted noise.
